exactly. i have a 30 gal external res that feeds up to 4 of the waterfarms.So, are you saying you have a system on a timer which feeds through the top basket until the excess runs up the blue tube, through the extension you’ve added to a drain?
a submersible pump, this manifold:

and some silicone aquarium tubing out to each waterfarm.
i only measure the EC of what's in my external res. i feed very lightly: usually 1 to 1.2 EC at maximum growth. 0.6 to 0.8 for veg and then 0.6 for end of bloom. 0.3 for seedlings.How do you measure the EC from the pots? If the run off is a mix off old nutrients & what’s just been added the reading you get from the run off would not be accurate. Or do you manually measure the ec in the pots before each daily top up?
the only thing i had to dial in was my nute recipe. i 've tried some brands that aren't pH stable for that long of a time and some additives will throw off pH too. if you wanted to spend a bit more money, a pH doser up/down would make it almost fool proof.
